What should be done with the tapered plug if there are deep scratches found during inspection?

Replacing the entire gas valve is the appropriate course of action when deep scratches are found on a tapered plug during inspection. Tapered plugs are crucial for ensuring a proper seal in gas valves. Deep scratches can compromise the integrity and functionality of the plug, leading to potential gas leaks and unsafe operating conditions.

A gas valve needs to maintain a tight seal to function efficiently and safely, and any significant damage, like deep scratches, can hinder that seal. Even if the plug appears to function initially, small imperfections can lead to long-term issues and safety hazards. Therefore, the safest approach is to replace the entire gas valve to ensure that all components are in optimal condition. This replacement minimizes the risk of failure, thereby ensuring compliance with safety standards and reducing liability in commercial kitchen operations.
